This invention relates to aircraft andin Figure 2 is a fragmentary View in sec-' particular to a device which takes advantage tion of. the forward end of the plane showing of some of the fundamental principles of the use of a rotor head, the under surface aerodynamics which willenable the aircraft of which, is adjacent a stator. g to rise vertically from the earth as well as a Figure 3 is an end view of the rotor head 55 propel the same forwardly. g as illustrated in Figure 2.

A particular object of myinvention is to F1gure4 1s an enlarged view in elevation provide in a heavier than air machine a roof the upper end of the vertically disposed tating member used in conjunction with a or llftlng rotor disk and its associated stator particles will through their action lower Figure 5 is a top plan view of my device the elfectof atmospheric pressure to advanas illustrated in Figure 4, the position of the tags of one surface thus providing a vertical frame legs being illustrated, upward thrust which will lift the plane Referringto the drawings in detail 5 infrom the ground or will propel it through dicates an aircraft of any vparticular for- I th i 1 v. i mation employing the acceptedwing'strucs A still further and equally important obture 6, landing wheel 7, tail skidS, body 9, I

This shaft face, the moving surface travelling athigh 16 carries exterior of the stator a rotor head speed so that velocity is imparted toair par- 17 which is so shaped that it carries out the ticles in the vicinity of. the rotating surface stream line effect of the craft and consewhereby the velocity of these particles will quently offers little resistance to the pas- ;tend toapproach the rotating speed of the sage of the ship through the air.

A11 aircraft compelling means comprising a fixed stator having a smooth face, a rotor substantially conical in shape and having a smooth outer surface and face adjacent the stator face, both the rotor and stator faces being substantially of the same area,

and slightly separated to constitute an air space, and means for revolving the rotor.

In testimony whereof I, BRYANT CHESTER,

have signed my name to this specification,
